    Roller arrangement with a movable inlet shield
    The invention relates to a device for forming a flat rolled, continuously conveyed Teigbandes comprising a first roller which is rotationally driven about a first axis of rotation, a second roller which is rotationally driven about a second axis of rotation, wherein the direction of rotation of the first roller of the direction of rotation the second roller is opposite and wherein between the first roller and the second roller, a nip for performing and Auswalzung a dough sheet is provided, a closing ring, which is arranged concentrically with the first roller and projects beyond the first roller for lateral sealing of the nip in the radial direction , And a conveyor for feeding the dough sheet to the inlet region of the nip. Furthermore, the invention relates to an entry plate for the roller assembly according to the invention, which is preferably movable via a movement device.
    Devices for forming a flat rolled, continuously conveyed Teigbandes are known and published in different versions.
    For example, Auswalzvorrichtungen are known, which are referred to in the jargon as Duomat. An upper and a lower roller are each side 2/20

    * .. · Haas Food Equipment GmbH rotatory and driven mounted on a machine frame. Between the two rollers, a nip for carrying the dough band is kept free. The supplied dough sheet has a greater thickness than the height of the nip. This will cause the dough sheet to be rolled out. When rolling it comes to a dilution of the dough strip. This results in a speed increase of the dough sheet after the pair of rolls and possibly in a broadening, i. in a lateral broadening of the band. In order to optimally use the roll width, the incoming dough sheet is guided close to the lateral edges of the rolls. Space for a lateral extension of the dough strip is thus not available.
    For this reason, roller arrangements are known in which the nip is laterally sealed in order to prevent the lateral expansion of the dough strip during rolling. As a result, a laterally closed nip is formed. In this nip occur high pressures of several bar. Thus, both the rollers and the nip laterally sealing the inlet plates must be sufficiently dimensioned and stable.
    In conventional roller assemblies, the inlet shield is rigidly connected to the machine frame and supported on this to intercept the pressure forces can. A disadvantage of this design is that during maintenance or when starting access to relevant parts is prevented by the inlet shield.
    If, for example, the conveyor belt of the transport device is to be exchanged, via which the dough strip is fed, then the inlet plate and optionally the entire roller arrangement must be dismantled. However, in particular a quick change of feeder belts to increase the efficiency of the entire system is absolutely necessary.
    Furthermore, roller arrangements are known in which the width and / or the shape of the nip can be adapted to one another via relative movement of the rollers. The sealing of the nip and the lead-in area is insufficiently given in these devices by conventional inlet shields.
    The object of the invention is now to provide a device for forming a flat rolled, continuously conveyed Teigbandes which is a qualitatively 3/20 Μ ········································: :: · ·. 51988 / gp / fi

    Fig. 1 shows an embodiment of the device according to the invention, in which a dough sheet 1 is passed through a first roller 2 and a second roller 4 therethrough.
    For feeding the dough sheet 1, a conveyor 10 is provided, which is shown schematically in the present illustration and not in its full size. The conveyor 10 comprises a conveyor belt 22, which is deflected around a deflecting body 21. The conveyor belt 22 is preferably driven by a drive.
    When deflecting body 21 leaves the dough sheet 1, the conveyor belt 22 and is funded by the inlet region 11 in the nip 8. The nip 8 is substantially defined by the opening formed between the two rollers 2, 4, the side inlet shields 12 and the end rings 9. The first roller 2 has a first axis of rotation 3 which, in the present representation, projects in a projecting manner.
    The second roller 4 has a second axis of rotation 5, which also extends projecting. However, the two axes of rotation 3 and 5 may be slightly entangled if necessary.
    According to a preferred embodiment, the second roller is designed to be movable relative to the first roller. In particular, this relates to the spatial position of the two axes of rotation of these rollers to each other. Thus, the nip can be changed in size and possibly in its shape. In order to enable the seal to each other even with a change in position of the rollers, the inlet plate 12 according to the invention is provided.
    The first roller 2 has a direction of rotation 6, which is opposite to the direction of rotation 7 of the second roller 5. As a result, the dough sheet 1 is conveyed through the nip 1. The first roller has a closing ring 9 on the side. This ring projects beyond the first roller 2 in the radial direction. In the present embodiment, the closing ring 9 also protrudes beyond parts of the second roller 4 in the region of the roller gap 8. As a result, the roller gap is at least partially sealed laterally. However, the end ring 9 can not be designed arbitrarily large, to laterally seal the inlet region 11 of the nip 8, since this otherwise structurally in 7/20 0 ····· 9 9 9 9 9 9 9 9 9 99999 9 9 9 9 9 9 9 99 99 9 9999 • · φ 9 9 9 9 9 9 > · 9 9 9 9 9 9 9

    Conflict with the conveyor belt 22 of the conveyor 10 would stand. For this reason, the inlet plate 11 according to the invention is arranged to be movable.
    The inlet shield 11 is in the present representation in the operating position. This means that in the illustrated position, the nip and the inlet region 11 of the nip 8 are sealed. The inlet plate 12 is connected via a moving device 13 to the machine frame 24. In particular, the entry plate is designed to fold over the movement device 13. The inlet shield 12 has a cutout 20. This is cut substantially round, wherein the curvature of the cutout 20 substantially corresponds to the radius of curvature of the lateral surface 19 of the end ring 9. By a linear or planar contact of the cutout 20 on the lateral surface 19 of the end ring 9 a sealing connection is given. Upon rotation of the first roller 2 and stationary inlet plate 12, there is relative movement and optionally to sliding friction between the two elements mentioned.
    Furthermore, the inlet plate 12 has a band cutout 23. The band cutout 23 has a shape that substantially corresponds to the contour of the conveyor belt 22 in the inlet region 11. In the illustrated operating position may be provided between the tape cutout 23 of the inlet shield 12 and the conveyor belt 22, a narrow gap. According to a further embodiment, the band cutout 23 of the inlet shield 12 can touch the conveyor belt 22.
    To seal against the second roller 4, the inlet plate 12 is pressed by a tensioning device 14 against the end face 16 of the second roller 4. The tensioning device 14 comprises a tensioning element 17 and a lever 18. The lever 18 has an axis of rotation about which it is rotatably arranged. About the clamping element 17, the inlet shield 12 can be pressed against the end face 16 of the second roller 4.
    Fig. 2 shows the clamping device as a detail of the section A-A. The second roller 4 is shown cut and arranged in the immediate vicinity of the first roller 2. The inlet shield 12 is pressed against the end face 16 of the second roller 4 to effect a seal. The pressure is applied to the 8/20 M by the tensioning element 17. 0 fl 0 0 00 fl

    Entry shield and further transmitted to the end face 16 of the second roller 4. The clamping element 17 protrudes in the present embodiment of the lever 18 of the clamping device 14. The clamping element 17 has a chamfer 25 in the present embodiment. If the lever is rotated about the lever axis 26, then the clamping element 17 moves away from the inlet plate 12 and the inlet plate loses the system on the second roller. This is done on the one hand via a slight elastic bias of the inlet shield, but possibly also by the movement of the rollers. If now the inlet plate 12 are tightened for sealing, the lever 18 of the clamping device 17 is folded, so that the clamping element 17 is brought into the region of the inlet plate 12. In order to prevent snagging or blocking of the tensioning element 17 and the inlet shield 12, the tensioning element 17 has a chamfer 25. At the beginning of investment of the clamping element 17 on the inlet plate 12, the edge of the inlet plate 12 slides along the chamfer 25, whereby the inlet plate 12 is pressed against the second roller 4. Optionally, also - or only - the inlet plate 12 have a slope to build up a pressure caused by relative movement force.
    Fig. 3 shows a schematic oblique view of a detail of the device according to the invention. The first roller 2 and the second roller 4 are rotatably mounted and driven according to the foregoing description and positioned at a distance from each other. Between the two rollers 2, 4, the nip 8 is provided. The first roller 2 laterally delimiting is at least one side, preferably provided on both sides in each case a closing ring 9. This cover ring 9 projects beyond the first roller 2 in a circular manner in the radial direction. Furthermore, the closing ring 9 preferably projects beyond at least a part of the second roller 4. As a result, the nip is at least partially sealed laterally. The conveyor 10 comprises a conveyor belt 22, which is deflected around a deflecting body 21. To seal the inlet region 11 of the nip 8, at least one inlet plate 12 is provided. Preferably, two inlet shields 12 are provided which laterally seal the inlet region 11 and the nip 8 on both sides. The inlet plate 12 is connected via a moving device 13 to the machine frame 24. As a result, a folding away of the inlet shield 12 is possible. Furthermore, a tensioning device 14 is provided. This is also indicated on the 9/20 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 7 9 • 9 3. , 9 99 99

    Machine frame 24 is arranged or supported. However, the part on which the tensioning device 14 is provided is hidden in the present illustration. The connection between the machine frame 24 and the lever 18 of the clamping device 14 is done via the lever axis 26. As a result, the lever 18 is rotatably arranged. Projecting from the lever 18, the clamping element 17 is provided. This protrudes in the direction of the inlet plate 12. FIG. 3 shows the clamping device 14 in the folded-away position. There is no contact of the clamping element 17 and the inlet plate 12 instead. Rather, the clamping element 17 in a free area, away from the inlet plate 12th
    In Fig. 4 the same arrangement, but shown in a different position. In this case, the clamping device 14 and in particular the lever 18 is rotated about the lever axis 26 such that the clamping element 17 is in contact with the inlet plate 12 and presses it against the end face 16 of the second roller 4. The remaining sealing of the gap takes place via the closing ring 9 of the first roller 2.
    This is in the maintenance position, in the one hand, the conveyor belt 22 of the conveyor 10 can be changed and on the other hand, the nip 8 between the first roller 2 and the second roller 4 can be maintained.
    The inlet shield 12 is folded away such that it is no longer pressed against the second roller 4. The plant for the first roller 2 and the end ring 9 of the second roller is not in the folded-away position. For fixing the inlet shield 12 may optionally be provided a connecting device 27. In the illustration of Fig. 4 and Fig. 5, this connection device is designed as a simple screw connection. For this purpose, a holder with a through hole is provided rigidly with the machine frame. Through this through hole, a screw can be inserted, which can be screwed into an opening of the inlet plate 12. The tensioning and sealing of the roller gap, in particular with respect to the second roller 4, takes place via the tensioning device 14, as described above. 10/20 ························································· ·· «· · · · · · · ······································

    According to a further, not shown embodiment, the inlet shield 12 can be pivoted away about any kinematic arrangement of, for example, a pivot lever. If necessary, the inlet shield can also be completely removed.
    In all embodiments, an inlet plate is provided, which is preferably made of plastic or, for example, made of bronze. Basically, any material is suitable, which can be referred to as a sliding material in the technical sense and has sufficient rigidity against the pressure of auszuwalzenden Teigbaden. In particular, it is important that at the points of contact with the moving parts, e.g. with the second roller or the ring of the first roller, the friction is kept low by a suitable material pairing. For example, this is given by a pairing plastic / steel, bronze / steel or similar sliding mating. 11/20
